USA Today has an interesting interactive graph on the changing religious landscape in the U.S.

Explore this interactive graphic showing data collected over 18 years from the American Religious Identification Survey (ARIS).

The 2008 results, to be released today, are based on 54,000 interviews with a margin of error of plus or minus 0.5%. It finds that, despite population growth and immigration adding nearly 50 million more adults, almost all denominations have lost ground since the first ARIS data was released in 1990.
